Screenshot

In LXQT, gnone-screenshot is not available and the existing lximage-qt -s is in my option, broken to beyond redemption. However, the lximage-qt team introduced screengrab instead in this issue. Hence, let's proceed to install it.

Install ScreenGrab

This step is to install ScreenGrab package:

$ sudo apt install screengrab -y

Configure ScreenGrab

This is tricky. Run the ScreenGrab application. Don't worry, it will snap a screenshot in the process.

$ screengrab

Once it's completed, you will be shown with the ScreenGrab display panel. Select the wrench to bring up the Option menu.

Configure Save Path

Configure Advanced Settings

Next is to configure the advanced settings. Most of the ScreenGrab functionalities are in manual mode. Hence, configuring these advanced settings to make it more semi-automatic mode as expected.

Save the Options

Once you're done with the options. Save it. Then exit that screenshot without saving it.

Update Hotkey

Now proceed to update the print-screen hotkey. Go to "Shortcut Keys" > "Print" > "Modify".

Update the command section with the type of screenshot you desired. Here's a help dump from ScreenGrab:

u0:~$ screengrab -h
Usage: screengrab [options]

  -r, --region      Take a screenshot of a selection of the screen              
  -m, --minimized   Run the application with a hidden main window  

I personally like region than any others.
